BGRABitmap Error: Asm: [movq mem??,reg64] invalid

I am having difficulty with BGRABitmap.  I downloaded the latest
version 8.9.2 after opening in Package -> Open Package File, I attempt
to compile but I have received numerous errors:

bgradefaultbitmap.pas(2821,3) Error: Asm: [movq mem??,reg64] invalid
combination of opcode and operands

I haven't found the offending asm code.  I wonder if the problem might
be a compiler flag setting -- e.g. AT&T vs. Intel.

The errors are all within the file BGRAdefaultbitmap.pas .  There are
about 25 of them.

While tracing back through the code, I came upon
BGRAPoligonAliased.pas which shows Intel code.

When I have encountered Intel code previously in Lazarus, I have had
to convert over to AT&T to get passed the problem.  I have looked at
the compiler flags, but don't see one dealing with AT&T vs. Intel. I
noticed that this version has only been released earlier today. There
might be a problem in the release -- small error somewhere, etc.
Hopefully, the developer can take a look.

In problematic unit, add {$asmmode intel} after {$mode <x>}{$H+}
switches.

I have the same error in my own code:
Code: [Select]/home/runner/work/ApusGameEngine/ApusGameEngine/Apus.Eng
ine.ShadersGL.pas(639,3) Error: (8007) Asm: [movq mem??,reg64] invalid
combination of opcode and operands
however, there is no ASM code in that unit. Moreover, this happens
only when the target is Linux and at the GitHub servers only: https://
github.com/Cooler2/ApusGameEngine/runs/4908563676?check_suite_focus=tr
ue
The same Lazarus version on my own PC compiles the code without
errors, so it looks very strange.
